UAS Development Submitted by Joel Thorsheim on behalf of Insitu The Boeing Company Frequency Management Services P.O. Box 3707 MC: 2T-22 Seattle, WA 98124-2207 206-544-6066 Office Why an Experimental License is Necessary: An experimental license is required to support development and testing of the UAS communications data link architecture. Operation Description: The operation involves experimentation using a Common Data Link (CDL) systems that will be used as the communications data link for a UAS. The initial phase of the experimentation will require ground testing of the data link from the UAS terminal to a ground control station terminal. During this phase of the testing the aircraft terminal equipment will be operated on the ground at Bingen, WA. The UAS communications terminal will transmit in the CDL mobile band (14400 – 14830 MHz), and the fixed ground control terminal will transmit in the CDL fixed band (15150 – 15350 MHz). No mobile air operations are required for the initial phase, and all communications tests will be conducted within the requested areas of operation. Follow-on testing will include actual mobile air to fixed ground station operations, and is anticipated to be conducted at Boardman Bombing Range, OR. Flight testing will demonstrate communications capability from ground to 10,000 feet.

Table (1) lists the aircraft terminal specifications, including frequency band of operation, transmitter output power, emissions, antenna types and gains, as well as maximum ERP. Figure (1) is a diagram of the aircraft terminal configuration.

Table (2) lists the ground terminal specifications, including frequency band of operation, transmitter output power, emissions, antenna types and gains, as well as maximum ERP. The ERP calculation takes into account various system losses between the transmitter output and antenna feed. Figure (2) is a diagram of the ground terminal.
